COIVEBIEI'ED TAIL LIGHT AN D STOP SIGNAL.

Application filed March 26, 1923. Serial No. 627,909.

The invention relates to vehicle lamps and has for its primary object the obtaining of a simple construction of combined tail light and stop signal as hereinafter set forth.

In the drawings: [FigureV 1V is a` perspective view of the lamp;. j Figure 2 is a front elevation partly in section;

' Figure 3 is a central longitudinal section,

A is the casing of any suitable form and provided at its front with the removable cover B. C lis a socket projecting from the rear of the casing for receiving a connector plug,v and D is a lamp socket within the j casing for receiving the bulb E constituting the tail light. v

To arrange the stop signal in the` same casing with the tail light, a second lamp socket F is provided, this being preferably arranged adjacent to the top wall of the casing. G is an inner casing surrounding the socket F and extendingforward to the cap B so as to prevent the assage of light between the compartments or 'the two bulbs. The casing is preferably of segmental form so as-to conform to the shape of the outer casing and its outer end is anged at G having a felt gasket G2.for bearing against a liner plate H. The plate I-I secures in place the glass panels or lenses I and J and if desired the letters'for the Word Stop maybe cut in a portion of the plate registering with the casing G.

The sockets D yand F are preferably mounted on an insulator block K, which is.

secured by the screws L to the lining plate L adjacent to the rear wall of the casing A. The plate L in turn is secured to the casing A and is provided with studs M projecting rearward through a ertures in the casingA, constitutingv means or mounting said casing upon its support. The socket member C has arranged therein two insulated spring contact members N and-N which project forwardly through apertures inthe block K. The con- 'tact N is positioned to register with the insulated contact of the bulb E, while the contact N engages a conductor strip O leading into'the lamp socket F and engaging the insulated contact member of the bulb for said socket. The sockets D and F are grounded upon'the'ca'sing and thus each lamp bulb is provided with an insulated contact and a .purpose of t grounded contact for completing the electric circuit.

The parts constructed as thus far described are assembled as follows: The socket C is secured to the lining plate L by a flange C engaginga countersunk portion of said plate. The insulator block K is then attached to thev plate by clamping screws .-1) and the casing G issleeved upon the socket F and attached to the insulator plate by screws Q. The liner plate L with the members attached thereto is then inserted within the casing A, the socket` C projecting through an aperture in the rear wall of the case and-being secured by a collar R having a threaded engagement with a .portion 'of screws Sy, which completes-the assembly.

In operation, the electric'. circuits can be' completed through the respective bulbs E by connections with the contact members N and N and the usual controlling switches (not shown). Normally only the bulb E is illuminated, the rays of which extendv through theI lens J and also through the window T in the bottom of 'the casing for illuminating the license number. The bulb inthe socket F is only illuminated when the stop signal is to be given and this bulb is preferably of greater candle power so as to produce a brilliant signal.

The construction organizedas described can be cheal'ly manufactured and serves the etwo independent lamps lwhich are generally used.

What I clalm as my Invention is:

auv

an outer casing, of an insulator block detachj ably secured within said casing, a plurality of lamp sockets having insulated contacts mounted on said insulator block, a connector i socket also mounted on said insulator blockv and projecting'. outward through an aperture 1n said casing, insulated'terminal cont-acts within said connector socket, means for respectively connecting the insulated contacts of said lamp sockets with said insulated terminal contacts within said Connector socket, contacts for each of said lamp sockets, means for grounding said contacts, an inner casing surroundi one of said lamp sockets, and a cap for said outer casin hav-. ing transparent panels, one of whic reg- 2. In Va vehicle lamp, the combination with` an outer casing, of an insulator block detachably secured adjacent to the rear wall of said casing, a. plurality of lamp sockets for separate `lamp bulbs mounted on said insulator block, a lining plate having a counter# sunk portion, a connector socket having a iange engaging said counter-sunk portion and projecting outward through an laperture in said casing, insulated spring contact members within said connector socket vwhich project forwardly through apertures in said insulator block, means\ for connecting said lamp sockets'with said spring contacts including a conductor strip leading into one of said lamp sockets and engaging an insulated vcontact member adapted to be on the bulb for said socket.

3. In a vehicle lamp the combination with an outer casing and a lining plate, of an insulator block detachably secured to said lining plate, a plurality of lamp sockets mounted on said insulator block and secured to said lining plata-,said lining. plate, insulator block and lamp sockets being insertable in said casing as a unit, and means for securing said lining plate to said casing.

4. In a vehicle lamp the combination with an outer casin and a lining plate, of an insulator block etachably secured to said lining plate, 'aplurality of lamp sockets mounted on said insulator block and secured to said lining plate an inner lcasing surrounding one of said vsockets and secured to said insulator block, said lining plate, insulator block, lamp sockets and inner casing being insertable in said outercasing as a unit, and studs on said lining plate projecting rearwardly.

through apertures in said outer casing constituting means for securing said liningplate to the outer casing and for securing sald casing to its support.
